Xylem System 5000 User Manual - Manual (Page 64)

The current temperature reading should be close to ambient but may be off by a few degrees.
The latitude and longitude at the site are listed if the GPS receiver is working and has acquired
the time and other GPS information.
There is general GPS information listing if the time has synced, when it synced, how many
missed syncs have occurred, etc.
The fail safe status is also listed on this screen and should always indicate it is ok.

Self-Test
The Self-Test option will either perform a Self-Test on the GOES Radio (H-2221) or show the most
recent Self-Test results (OmniSat/SE-1200). Self-Tests can take several minutes to complete. Radio
hardware including temperature, battery voltage, and flash (memory) will be checked through
these routines. There are several checksum or CRC tests here that return OK or an Error. If a CRC
test fails it may be best to call technical support to discuss the problems. There are also some
battery and temperature tests. The temperature test often fails and it is normal if the temperature
is not at room temperature. The temperature reading should be close to ambient temperature.
Send ST Carrier (90 sec)
This option is used to test the RF power output when the signal is not being modulated. This test
allows for the true power of the transmitter to be measured. This will run for 90 seconds or until
the Stop button is pressed.
Since the carrier is sent on the self-timed channel and is normally used as a local power test, it
should only be used when the unit is connected to a dummy load. Transmitting on this channel
while connected to an antenna will interfere with other users and other sites.
A couple of things to watch for is the power reading on the watt meter to see that it holds steady
and does not drop off in time as the test is used for a minute or more. The other thing to watch is
the battery voltage level at the radio to see that it does not drop off significantly also.
When using this option, it is recommended that Scanning is turned Off.
Send Random Tx
To test sending a random message, this option will send the message “This is a test message”
over the set Random Channel at the baud rate specified in the Random Options.
Specific to the H-2221 Diagnostics screen are the following options:
Config
The Config button retrieves the current transmitter settings collected from the GOES Radio.
This information includes all of the information set within the GOES menus on the System
5000.
